NAME¶

lparnumascore - display the NUMA affinity score for the running LPAR

SYNOPSIS¶

lparnumascore [-c | -d ]

DESCRIPTION¶

The lparnumascore command can be used to display the NUMA affinity score for the running LPAR. Each score reflect the amount of resources the Linux kernel is seeing as bound to a node while the hypervisor has moved that resource to another node.

The score is a number between 0 and 100. A score of 100 means that all the resources are seen correctly, while a score of 0 means that all the resources have been moved to different nodes. There is a dedicated score for each resource type.

OPTIONS¶

-c <resource type>

Display the score for this type of resources. The valid resource types are "mem" for memory, and "cpu" for cpu's. By default, the score for each of supported resources is reported.

-d <detail level>

Enable debugging output. When displaying memory information this flag will also enable printing information about LMBs not currently owned by the system.
